Clear Acrylic Replacement Knobs

Ilco AG30 knobs replace worn or dated hardware on compatible locksets. The clear acrylic body resembles crystal glass and pairs with a brass-finish shank for a decorative accent. Each knob uses a square, straight spindle threaded on both ends and includes set screws for secure attachment. Lock mechanism is sold separately.

Upgrade From Basic Knobs

The AG30 suits doors where the existing knob is cracked, discoloured or stylistically mismatched. Its fluted crystal-look design refreshes the appearance without replacing the entire lock body. The change is worth it when the current spindle is square and straight, matching the threaded-on-both-ends specification. Buyers who need a different spindle profile or an integrated lock cannot use these knobs.

Build Integration

Installation requires a compatible Ilco 215-04-51 lock body that accepts a square drive spindle. The included set screws fasten the knobs to the threaded spindle ends, completing the trim. No additional finish-matched hardware is supplied, so coordinating hinges or strike plates must be sourced separately. Builders who need a complete locking assembly must purchase the lock unit on its own.

Questions about this item

What spindle size and shape do these knobs require?

The AG30 knobs use a square, straight spindle that is threaded on both ends for a secure fit.

How are the knobs secured to the spindle during installation?

Tighten the supplied set screws against the flat sides of the square spindle; skipping this step lets the knob spin freely.

When should the clear acrylic knobs be replaced?

Replace them if the acrylic cracks, the fluted crystal pattern wears smooth, or the brass-finish shank corrodes.
